I was looking through my archives of Performer stuff I was interested
and
ran across the thread titled "Earthsky with 3 channels" posted by
Joaquin Casillas in March of this year. I checked the archives and saw
no resolution to the problem. To refresh, the origional posting was:
I am working in a 3-channel visual simulation and I am having trouble
with the pfEarthSky model (mode PFES_SKY_GRND or PFES_SKY_CLEAR).
Whenever I do a 'hard' pitch turn, the earthsky model on the left and
right channels are not drawing properly. It seems the framebuffer is not
being cleared correctly in the ground area, like if I was using the
PFES_SKY mode. The channels are arranged in a channel group, having the
left and right channels a heading offset, and the earthsky model
attached to the middle (master) channel.
I am using Performer 2.2, Irix 6.5.1 on an Onyx2 IR.
Any help would be appreciated.
Well, I see the same behavior on my Onyx2 IR/Peformer 2.2/Irix 6.5.3 and
I believe this to be a bug in the EarthSky model. As explained by
Joaquin, it occurs in a high pitch turn and the ground part of the
channel
doesn't clear. For me it is only in the left and right channels and not
the center channel. I suspect it is because of the angular offset for
the left and right channels is not being accounted for when the channel
clear takes place.
I checked the archives and didn't see any final resolution on this.
Does
anyone have an answer on this one???
